RESILIENT TIRE.

following" to be a full, clear, and exact descript-ion of the inventiomsuchas will en able others skilled in the art to which 1t appertains to make and use the same.

My'invention relates to \{ehicle tires. It has for its object to provide a resilient tire which is entirely puncture proof and,

therefore, much more durable than the ordinary pneumatic tire.

Another object is to provide for varying thetension or resiliency of the tire to accord with the weight of the load.

Further objects will become apparent from the following description.

The invention consists in the features of construction and combinations of parts hereinafter descrlbed and specified in the claims.

In the accompanying drawings, illustrat ing the preferred embodiments of my invention: Figure 1 is a side view of a part of a wheel carrying one of my tires, a portion of the tire'and felly of the wheel being shown in central section. Fig. 2 is a cross section on the line of Fig.1. Fig. 3 is a similar view of a modified construction in which a' smaller inner tire is used. Fig. 4 is a similar view of a modified construction in which no inner tire is used. Fig. is a similar View of a modified construction in which no outer tire is used, and Fig. 6 is a broken side view of the last modification.

Referring first to Figs. 1 and 2 of the drawing, 1 designates the felly of the wheel which has outwardly extending flanges 2 secured to it by any suitable means, such as the bolts 3. Between these flanges and arranged crosswise on the outer surface of the folly are la 4 spaced equidistant apart and serving as guides for plates or shoes 5 which conform on their inner faces to the folly but are flat on their outer surfaces. Outwardly extending tables 6 are formed on each of the shoes Said tables are stepped, as at 7, to provide for centering and retaining helical springs 8 arranged interiorly of larger similar springs 8 The springs of each pair are coiled in opposite directions Specification of Letters Patent.

whereby the force of said springs is directed in true radial lines. A bumper 90f rubber or other suitable flexible material is fixed in a socket in the outer face of each table, or otherwise secured thereto. Said bumper in reality constitutes one of the concentric circular steps of the table, and it extends into the spring 8.

An outerI shoe 10 having tables 11 and bumpers 12, similar to those on the shoes 5, is arranged above each of'said shoes 5. Said bumpers 12 and 9 are adapted to be brought together when the springs are compressed. Each shoe 10 hasa fiat under surface and a curved outer surface conforming to the curvature of the wheel. Said shoe 10 is equipped with inwardly extending lugs 13 which are guidedbetween the shanks of bolts 14 passed transversely through the flanges 2 appoints arranged radially above the lugs 4 on the felly. The shoe 10 is further guided and retained against endwise movement by a slotted lug 15 arranged at the middle of said shoe and engaging a bolt :.16 also passed transversely through the The shoes 10 are grooved on their outer faces to receive a solid tire 17. Plates 18 are let into the under surface of said tire and span the spaces between the adjacent ends of the shoes 10 whereby the tire is prevented from entering between said shoes and the unrestricted action of the latter is insured. An outer tire or covering 18 is placedover the tire 17 and is secured by the turned clencher-forrn edges 19 of the flanges 2.

In order to adjust or vary the tension or resiliency of the tire to accord with the weight of the load, I provide bolts 20 passed through the felly with their heads projecting outwardly therefrom and their other extremities engaging sockets in the inner faces of the shoes A nut 21 is set in the outer surface of the felly around each bolt, the

working loose by reason of the jars inci dent to the running of a vehicle mounted on wheels provided with my improved tire.

As illustrated in Fig. 3, a small flattened inner tire 24 may be employed instead of the round tire 17, shown in Fig. 2. In Fig. i, the outer shoe is made in skeletond'orm, to secure lightness, and no inner tire is used. It will he noted that the outer shoes in all. of these constructions are capable of moving in and out between the flanges 2, and are cushioned hy the springs 8 so that jars are al'isorhed by my tire in the same manner as the ordinary pneumatic tire, and even to a greater degree. At the same time, it is 'iert'ectly puncture proo'l because there are no pneumatic tires employed. As illus trated in l i 5 and (3, the outer tire may he dispensed with and a single tlre used.

ment with said lugs and between the adja- Such a construction, however, will not he dust proof, so I provide slots 26 in the flanges 2 for the discharge of dust or water which may enter between them. These slots are not force-d in the flanges when an outer tube is used because the tire is then thorongl ly dust and water proof.

i. do not limit myself to the exact details of constru' tion herein shown and described as they may be changed without departing from the irit or sacrificing the advantages of my llimlllltill. For instance, any other resilient nuttcrial may be employed instead 1 When springs are used, the

of the springs. nun'iber and thickness thereof may be varied to suit the load. l, therefore, reserve the right to n'ialte such changes as fairly fall within the scope of the appended claims. may he noted that the tires may be fastened to the shoes in any suitable manner.

l claim:

1. The combination, with a folly of a wheel, and tire, of shoes on the inner surface of the tire, other shoes on the outer surface of the telly, tables on the facing surfaces of said inner and outer shoes, said tables having concentric circular steps thereon, helical springs interposed between said shoes and engaging the steps on said tables, bumpers arranged concentrically ot' the steps of said tables farthest from their respective shoes said bumpers being made of resilient material and extending within said springs where they are adapted to be brought together when said springs are compressed.

2. The combination, with the folly of a wheel, and a tire, of adjustable shoes on the outer surface of the telly, other shoes on the inner surface of the tire, springs interposed between said shoes, radial lugs on the folly to guide the inner shoes, flanges secured to sa id telly and extending outwardly to the sides of the tire, and bolts arranged transverscly through both flanges in radial alinerent ends of the outer shoes for guiding the latter.

3. The con'ibination, with a folly of a wheel, and a tire, of adjustable shoes on the outer surface of the folly, other shoes on the inner surface of the tire, springs interposed between said shoes, radial lugs on the telly to guide the inner shoes, flanges s0- curcd to said folly and extending outwardly to the sides of the tire, bolts arranged trans versely through the flanges in radial alinement with said lugs and between the adjacent ends of the outer shoes for guiding the latter, and plates conforming to the outer surfaces of said outer shoes and to the inner surface of the tire and arranged hetwcen them so as to span the apaces between said shoes for the purpose specified.

In testimony whereof, I ailix my signature, in presence of two witnesses.
